Duh. Take two fresh, steaming,
molten slices of dollar
pizza from your local, neighbourhood or (if you're lucky) downstairs
parlour. Lovingly stack your cold,
leftover piece against the top faces of those two, frigidly
nestling among their gooey
cheese and toppings initially, but invariably warming sooner than not to their erotic attentions in a culinary
menange a trois.
Of course, any such sinful indulgence must bear a fitting and appropriate punishment. Thus, before your slices begin enjoying themselves too much... you gobble them down, one two three in a triple-decker pizza sandwich.
Ask a stupid question...
